Hi,
anyone ever cored a hole (for waste pipe 125mm) through a random rubble wall - about 2 feet thick?
The outer and inner stones are too big to remove which seems like a common solution - bit worried that once I've cored the outer stone the random rubble middle will be an issue and jam the drill.
I'd hire a dedicated core drill with clutch etc. Only ever done this on brick/block but this is whinstone which from the pilot hole is like drilling metal!
Cheers.
